物流配送中电子地图数据结构的探讨

GIS、GPS、GSM技术对于现代物流配送来说是三项极为重要的技术．物流配送系统利用GIS和GPS技术来实现配送车辆的跟踪和定位以及路线的优化．而电子地图是GIS、GPS、GSM技术在物流配送应用中的核心部分之一．因此明确电子地图所用的数据结构。有着至关重要的作用。为此，本文提出了一种适用于物流配送中的电子地图的数据结构，并对其进行相关的逻辑描述，以提供恰当的逻辑方案来建立地图空间数据库，为物流配送中的电子地图数据的标准化采集提供依据，最后对应用于物流配送中的电子地图的矢量化过程进行了初步探讨。

Research on Database in Digital Map for Logistics Distribution

GIS/GPS/GSM are very important for logistics delivery, route optimization and to track vehicle location in real time. Electronic map is one of the key parts for GIS and GPS which are applied to logistics dehvery. And it is important to make sure the database structure of the electronic map. It presents a kind of database structure suitable for electronic map in logistics delivery and describes it logically. In this paper, a felicitous logical model is applied to establish spatial database and the standards of map-data collecting in logistics delivery. Finally, procedures on electronic map vectorization are discussed prehminarily.
